2. Safety Information

Always adhere to the following safety precautions to prevent personal injury or damage to the devices.

• General Safety: Do not operate the devices if they appear damaged or if the casing is open. Ensure your hands are dry before handling electrical components.
• Multimeter Safety:
  • Do not apply voltage or current that exceeds the maximum rated values specified in the specifications section.
  • Always disconnect the test leads from the circuit before changing functions.
  • Use caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC. These voltages pose a shock hazard.
  • Ensure the correct function and range are selected before making measurements.
• Tachometer Safety:
  • Do not stare directly into the laser beam. Avoid directing the laser at people or animals.
  • Use the device only as intended for RPM measurement.
  • Ensure the measurement area is clear of obstructions and moving parts are safely guarded.

4. Setup

4.1 KAIWEETS Smart Multimeter KM602

• Charging: Connect the provided USB-C cable to the multimeter and a standard USB power adapter (not included) to charge the internal battery. The display will indicate charging status.
• Test Lead Connection: Insert the red test lead into the 'INPUT' jack and the black test lead into the 'COM' jack for most measurements. For current measurements, refer to the specific instructions in the operating section.

4.2 KAIWEETS Non-Contact RPM Tachometer KTA01

• Battery Installation: Open the battery compartment on the back of the device and insert the required batteries (typically AAA, refer to specifications) ensuring correct polarity.
• Reflective Strip Application: For accurate RPM measurements, attach a small piece of the provided reflective strip to the rotating object. Ensure the strip is clean and securely adhered.

5. Operating Instructions

5.1 KAIWEETS Smart Multimeter KM602

Press the power button to turn on the multimeter.

5.1.1 Smart Mode (Auto)

Upon power-on, the multimeter typically defaults to Smart Mode. In this mode, it automatically detects and measures:

• DC Voltage
• AC Voltage
• Resistance
• Continuity

Simply connect the test leads to the circuit or component, and the multimeter will display the appropriate measurement.

5.1.2 Manual Mode

Press the 'FUNC' button to cycle through different measurement functions if you need to select a specific mode not automatically detected by Smart Mode, or for specialized measurements.

5.1.3 Specific Measurements

• Voltage (AC/DC): Connect test leads in parallel with the circuit.
• Current (AC/DC): Connect test leads in series with the circuit. Ensure the correct input jack is used for current measurement (e.g., 10A or mA).
• Resistance: Connect test leads across the component when power is off.
• Continuity: Connect test leads across the circuit or component. An audible beep indicates continuity.
• Temperature: Use the provided thermocouple and select the temperature function.

5.2 KAIWEETS Non-Contact RPM Tachometer KTA01

Press the power button to turn on the tachometer.

5.2.1 RPM Measurement Procedure

1. Apply Reflective Strip: Tear off a small piece of reflective strip and stick it onto the object to be measured.
2. Aim Laser: Turn on the tester, select the mode (if applicable), and aim the laser at the reflective strip area from an appropriate distance.
3. Start Measurement: Press the 'TEST' button to initiate the measurement. The RPM reading will be displayed.
